UCTRONICSfor Raspberry Pi 4 PoE HAT with Cooling Fan, Mini Power Over Ethernet Expansion Board for Raspberry Pi 4 B, 3 B+ and Rackmount

This is everything I wanted in a Raspberry Pi rack mount! My Pis fit perfectly with their PoE hat so all I need is an patch cord. And the HDMI adapter makes it super easy to troubleshoot anything that requires a monitor.Also support is great. My package came with one HDMI adapter that was just enough crooked that it wouldn't fit on my Pi. I sent them a message and they immediately shipped me a working replacement. I'm happy!

All 4 USB to SATA adapters were out-of-box failures. I tried four different SSDs that worked with another adapter I have. When connected to a Windows PC I get constant connect and disconnect chimes. When connected to a Linux PC I get no response at all.

This is a really low profile POE Hat or the RPi 4B. It is very quiet and fans spins up/down based on load. Entirely appropriate for a Pi that is in a rack mount orientation.

Vielleicht ein bisschen teuer, aber wirklich sehr passgenau und gut! Auch die „Marquardt 203.007.013 Blindstücke“ passen genau in die Schalter-Aussparungen.

These little blank plates are quite expensive for what the are, but I wouldn't have minded if they did their job well. These don't create a totally airtite seal and allow a lot of air to bypass the cover plates due to the way the bend is performed. This wouldn't usually be a huge issue but in a rack soon to be fitted with seals and filtration for use in a dirty environment it requires a bit of extra work with tape, which could be used from the start for far cheaper!
